Is there anyone out there still using TDK RX11s and interested in sharing experience with a guy that has the dubious distinction of owning 2 of the beasts. They have great potential but stoppages due to parts inspection errors are killing me. Not a

Does anyone know the correct way to measure the pitch of the cavities between the rows and columns of waffle trays? Everytime that we measure using a caliper, it is always off. Is there a formula to use to determine the exact center of the cavities?
